Synodontis ocellifer Breeding Guide

The widespread West African Synodontis ocellifer has no documented home-aquarium reproduction; only genus-level wild spawning notes exist.

Overview

Synodontis ocellifer is widespread across northern and western African rivers, recorded from ten countries including Burkina Faso, Cameroon, Chad, Gambia, Ghana, Guinea, Mali, Niger, Nigeria and Senegal, in the Chad, Niger, Volta, Senegal and Gambia basins. It reaches a maximum total length of about 49 cm. As an omnivore it feeds on insect larvae, algae, gastropods, bivalves, sponges, crustaceans and the eggs of other fishes.

Sexing

No dependable external sexing method is described. Females are reported to be slightly larger than males of comparable age, but this is not a reliable field marker.

Spawning Behavior & Trigger

For the genus, spawning is reported during the flooding season between roughly July and October, with pairs swimming in unison. Growth is rapid in the first year and slows with age. These notes are general and have not been confirmed for Synodontis ocellifer specifically.

Egg & Fry Care

No documented account of egg or fry development is available for this species; reproductive knowledge for the genus is largely confined to egg counts from gravid females.

Common Challenges

The lack of an established spawning method, combined with the large adult size, is the principal barrier to captive reproduction of this riverine species.
